Abstract

Virtual Reality (VR) technology is changing the way of perceiving the digital world. In initial VR market, HMD device and VR game market formed the mainstream, but with increasing VR/AR contents and production software since 2017, it is leading the development of the entire VR market. Therefore, it is urgent to develop the manufacturing and production techniques of VR video contents that can induce and keep the immersion of the viewer. This study aims to conduct a specific case analysis of VR animation among VR video contents based on depth perception cues for immersion and find the directivity of visual depth production technique to keep and improve the viewer’s attention and immersion and also to make suggestions. Through the analysis of production process and scene sequence of <Back To The Moon>, the 15th VR animation of Google Spotlight Stories, this study concentrated on psychological depth perception factors so that the viewers could perceive the images in three-dimensional ways and be immersed in them. <Back To The Moon> has five sequences, each of which has unique color and mood. In the nature of the work, depth is used appropriately for production in space to induce viewer’s immersion. This study searched the cases of VR animation as the existing preceding studies and examined the researches on sense of immersion and spatial depth perception. The role of depth perception among perception factors was important to maintain the sense of immersion and accordingly, through video scene analysis of <Back To The Moon>, this study substituted 9 depth perception cues into 5 sequences for analysis and examined the frequency of use. As a result, it was found that the frequency of use appeared higher in order of scope of view, advancing color and receding color, relative height, overlap, shadow, and atmosphere penetration, and it is judged that if VR animation production is prepared based on depth cues, viewer’s visual immersion can be maintained and this study is significant in that it presented a guideline for production techniques.
